Yellow-cheeked vole, Microtus xanthognathus
The yellow-cheeked vole, or taiga vole, is an extant species of rodent that is currently found in central Alaska and northwestern Canada. As with many other rodents, this species serves as a good proxy indicator of local paleoenvironmental conditions, and its presence in Wisconsinan-aged deposits in the Midwestern U.S. indicates that regional temperatures were much cooler during this period.
